. A new Chandra image of M51 contains nearly a million seconds of observing time. The data reveal hundreds of point-like X-ray sources within what is nicknamed the "Whirlpool Galaxy." Most of these point sources are X-ray binary systems with either a neutron star or black hole orbiting a Sun-like star. The composite image consists of X-rays from Chandra (purple) and optical data from Hubble (red, green, and blue). X-ray: NASA/CXC/Wesleyan Univ./R.Kilgard, et al; Optical: NASA/STScI
